TAs much as I've admired Nick Park's short films (the justly acclaimed "Wallace and Gromit" series ), I had doubts that his unique style, with its children's-board-book design and pop-eyed, oval-faced characters, could sustain an entire feature. Park's films play on a contrast between simple, comical visuals and settings that border on banality: the soft-spoken Wallace, a Northern Englander with a fondness for home-made inventions, thinks nothing of building a space-ship or encountering a criminal mastermind (a penguin!). But he can be driven to ecstatic exclamation by a plate of cheese. The zoo animals in the Academy Award-winning "Creature Comforts" sit in their cages chattering about their surroundings like suburban cottage dwellers. Park's films are much better at finding new ways of looking at the mundane than at telling stories.
